[CMake] Getting at the final compiler/linker string for a given library

[Clifford Yapp]

Does anyone know if there's a way, given the full path find_package result:

/usr/lib/libfoo.so

to have CMake report what the eventual "-lfoo" entry will be on the
compiler/linker line?  I need to report out that information into a
file independent of CMake's logic, and so far I haven't been able to
zero in on how to get at it.

Thanks,
CY
